What is the best flat hike in the Bay Area?

You might look into some of the hikes listed here.

Limantour trail at Pt Reyes is relatively flat – a little incline down the dunes then along the shore.

How far do you want this hike to be?

The redwood hike at Muir woods is relatively flat.

I have often taken my kids to:
Los Gatos Creek Trail
Shoreline @ Mt. View
Rancho San Antonio County Park

We ended up going to Half Moon Bay and doing this hike
It was beautiful and definitely flat and easy – I would recommend it for anyone looking for a flat hike…really more of a walk than a hike.

One very flat hike (or maybe it is just a “walk”) is to walk the entire expanse of the Golden Gate Bridge.

@answerjill I walked through the Presidio and across the bridge to Sausalito once, then took the ferry back to SF. That was a nice hike.
